A conceptual model of power supply for the integrated grid of high-speed railway transport in Russia

The strategy of railway-transport development in Russia until 2030 and beyond involves the application of new technologies ensuring the competitiveness of Russian railways, which act as one of the key growth factors of the economy and its system-forming sector in the transportation industry of Russia. The article discusses the main factors and breakthrough technologies on the basis of which an integrated grid of high-speed railway connection is created. Paramount importance is given to increasing the speed of passenger and freight trains, combining high-speed railway lines into a single grid to provide an agglomeration effect, mobility, energy efficiency, and environmental safety. One of the priorities is the factor of reliable and safe power supply of competitive railway connections, for which a conceptual model of railway power supply is developed.
